I would check out the Olight Javelot Pro Javelot Pro Powerful Spotlight Flashlight - Olight Store Mainly because of how long the run time is. It does have enough throw. 1080 meters
LIGHTING LEVELS
LEVEL 1 (lumens) 2100
Run-time LEVEL 1 2100 lumens (~1000lm); 10 mins/ 130 mins
LEVEL 2 (lumens) 600
Run-time LEVEL 2 5hours.
LEVEL 3 (lumens) 150
Run-time LEVEL 3 23hours.
LEVEL 4 (lumens) 15
Run-time LEVEL 4 8days.
Yes but they can’t throw 800 meters…
1080 is the theoretical throw, you can guess half of that of usable throw.

Is it dangerous to sail around the world?
What about encountering pirates ?
You won’t be illuminating objects on a distant shore with it, but if I were headed into that sort of environment I would absolutely have an HDS with me. Rock solid, super reliable, built to take a beating in all sorts of environments. The guy who makes them is a caver and built a flashlight he can trust his life to. I’d probably want something else too, something larger and more powerful, but the HDS would definitely be with me too.
I'd rather encounter those than pirates!

Auto corrections on phone hahah
After al suggestions above I still think you would be most happy with a thrunite tn40 or 42 and maybe the C version if you want to charge in your light.
The lep lights have a far to narrow beam. You will be waving it around like a lightsaber to see something.
Adhara,
How is the tint on the Maxtoch with no filter? Is it as blue/ saber like as the W30? (I love the saber look, yet my eyes choose warm > neutral > cool every time). Any difference in diameter/size of beam? The distances we are talking about are so far anyway, I don’t believe a small difference in throw would make any impact on my buying decision, unless that difference is significant. I love the W10 CRI beam tint posted in another thread…looks so nice! Now seeing the W30 is out there in high CRI, the tint feels like it could be the deciding factor. I am also seeing a premium for the CRI edition, narrowing the cost gap between the Xsword and W30 CRI. I’m interested in your take.
Thank you kind sir!

On the plus side, you could make the “fwooom fwooom” sound effects while doing that…
Still, “two is one, one is none”, especially out on the ol’ briny, so I’d get a WEP for looooong-distance throwing, a pair of big zoomies (Cometas/Z1s, Brynites, etc.) for medium distance throwing, and even a big honkin’ Q8 for closer more general-purpose use.
Could you clarify this? The Maxtoch web page Contactcr linked to says the light has an LED, not LEP, with 1900m throw. The Acebeam claims 2400m throw. Which model Maxtoch do you have, is it different from the linked one?
Help me out please, I am confused. :person_facepalming:
What does “LEP” stand for or mean??
I clicked the link & find no mention of “LEP”.
What am I missing??
Here’s an explanation from Weltool who also has a LEP light:
Laser Excited Phosphur
That’s when you use strobe.
@ contactcr…. Thank you for the link… that explains a lot. :+1:
One more question. If someone clicked on the Maxtoch link and did not know that was a “LEP” light, what in the written description would tell them it was??
.
…
@ KB …. “Laser Excited Phosphors” … Thank you…. 
I guess I ’b’ behind the times & cutting edge a mile or two. 
I have some experience with night time boating and I suggest you bring two, the reason is when it’s a calm, clear night, a reflectored thrower (like the TN42 or the lighter Astrolux/Mateminco FT02 or FT03/MT35mini) would be enough but when the weather gets foul, wet, and water splashing from waves, foggy, etc., a reflectored thrower will show you almost nothing but a wall of fog or droplets, then you be thankful an ashperic or LEP-type for penetration would be your best illuminating tool.
